Ru-Ni/Al2O3催化马来酸二甲酯加氢性能研究
Study on the catalytic hydrogenation of dimethyl maleate over Ru-Ni/Al2O3
摘要
Abstract
A series of Ru-Ni/Al2O3 catalysts were prepared via adsorption-precipitation method,using Al2O3 as the support and RuCl3 ·xH2O and Ni (NO3)2 ·6H2O as precursors.Effects of pretreatment conditions and the amount of Ni on the catalytic behaviors of the catalysts were investigated.The catalytic activities of Ni-modified Ru catalysts increased with the increase of the Ni content firstly and then decreased.The highest hydrogenation activity was obtained as the atomic ratio of Ni ∶Ru is 6∶1.The catalytic activity of Ru1Ni6/Al-fresh subjected to reduction at 200 ℃ has no significant difference with the sample reduced at 400 ℃,reaching to 1.5 times that of Ru/Al2 O3 with the same pretreatment.Based on the results of XPS,XRD and H2-TPR,the reason for the promoted catalytic effect of Ni was disclosed.It was found that the dispersion of Ru could be improved as the promotion of Ni,resulting in the improvement of the catalytic performance of the Ru catalyst.关键词
